Lutron SL-4010 Digital Sound Level Meter
Overview:
The Lutron SL-4010 Digital Sound Level Meter is a robust, economical, and precise handheld instrument manufactured in Taiwan, designed for accurate noise measurement in various environments. Classified as an IEC 61672 Class 2 sound level meter, it is suitable for environmental and industrial noise assessment. The meter features a durable, lightweight ABS-plastic housing case, enabling convenient one-hand operation. It utilizes a highly accurate electric condenser microphone for long-term stability and precise readings.
Key Features:
Precision and Display:
• Large LCD Display: Equipped with an 18 mm (0.7 inch) LCD, offering a clear 3 1/2 digit readout, easy to view even in bright ambient light conditions.
• High Accuracy: Utilizes a condenser microphone for high accuracy and long-term stability in measurements.
• A-Weighting Network: Features the "A" frequency weighting network characteristic, which simulates the human ear's response to sound.
• Fast Time Weighting: Defaults to the "Fast" time weighting characteristic mode, simulating the human ear's response time.
Functionality:
• Data Hold: Includes a Hold function to instantly freeze the displayed measurement value.
• Calibration: A built-in adjustable VR (Variable Resistor) allows for easy external calibration, typically set at a 94 dB level using a screw driver.
• Range Warning: Incorporates a warning indicator system for both over-range and under-range conditions within the three measurement scales.
• Low Power Consumption: The LCD contributes to low power consumption, and a dedicated indicator alerts the user when the battery is low.
• Durable Design: Constructed using durable, long-lasting components housed within a strong, light weight ABS-plastic case.
Applications:
The SL-4010 Sound Level Meter is a versatile tool widely used across several fields for environmental and industrial measurement, including:
• Industrial sites and facilities
• Noise monitoring
• Outdoor measurements
• Building acoustics
• Assessment of noise levels in areas such as molding and heating environments
• Workplace and entertainment venue noise analysis
• Road traffic noise assessment
